You're in South Florida in the middle of winter. What else is there to say? This is my favorite marathon to run. I love that you get a chance to meet so many people from different countries, mostly Central/Sourh America. Of course Florida is flat so the course is as well. You start at the Triple A (Home of the Miami Heat), run thru South Beach, back to downtown Miami, through Coconut Grove and back to Bayfront Park. The course crosses Biscayne Bay 3 times. It is the most scenic course to run. The downside was that it was a humid and warm weekend which made my time slower than I planned.
I go to the expo on Saturday in SoBe then head up to Gulfstream Park for some live horse racing. Takes my mind off the marathon! But the race goes off at 6am the following day so I am in bed very early Sat nite. It is funny parking 4:30am at a garage in SoBe and having people who have drunk all nite (and are probably drunk as a skunk) wishing me luck as I am walking to catch the shuttle to the start.
But what made this race special was that this was held the same day as the Super Bowl. My beloved Seahawks were in it and were playing 25 miles from home. I was wearing a Seahawks tech shirt and had a lot of spectators wishing me luck. After the race I got back to the hotel,took a nap, and enjoyed one of my best nites as a sports fan.
The only negatives,if any, could be parking and the weather if you are not prepared to run in warmer temperatures than what you've been training in. But it's worth the trip. Again Florida in wintertime!
